New study led by South African scientists reveals how sea-ice #microbes survive the #SouthernOcean’s harsh winter, with implications for #climateChange
This study further reinforces the importance of the Southern Ocean marginal ice zone as a critical hotspot for global #sulfur cycling where #biogeochemical processes for climate regulation are enhanced.

"PLAIN LANGUAGE SUMMARY: River floodplains are integrative ecosystems in which diverse processes operate together to maintain river health. Floodplains are as critical to river health as the channel itself, yet floodplains lack the legal protections afforded to river channels in many countries.
KEY POINTS
• A river floodplain is an integrative physical, chemical, biological system and a key component of a river corridor
• Contemporary societal perceptions and regulatory frameworks do not reflect this scientific consensus...”

`We find that upper-#ocean dissolved iron #dynamics were decoupled from those of ligands, which necessitates a process by which dissolved iron escapes ligand stabilization to generate a reservoir of authigenic #iron particles that settle to depth. When this ‘colloidal shunt’ mechanism was implemented in a global-scale #biogeochemical model, it reproduced both seasonal iron-cycle dynamics observations and independent global datasets when previous models failed`

The most computationally expensive part of such models is the transport (by #advection and #diffusion) of #biogeochemical #tracers (zoo and #phytoplankton #nutrients, organic and inorganic #carbon, etc) with the #ocean #flow.

The more tracers we include to represent the complexity of #ocean biogeochemistry, the slower are the model runs. Same problem arises when the #spatial #resolution of an #ESM increases.

Biogeochemistry models can become a bottleneck in #ESM computations. 2/

It is challenging to represent the #CoastalOcean #CarbonCycle in an #EarthSystemModel.

Due to a relatively coarse spatial resolution, #global models do not resolve the complex coastal #biogeochemical dynamics. #Regional models don't get the open-coastal ocean exchange at their boundaries.

Find out how we address this challenge with a telescoping #HighResolution #model:

This is an example on how #dust is generated in the Southern Hemisphere from one of the major dust sources. While not as a big producer as some regions in the N. Hemisphere, its location makes it important for #biogeochemical and #paleoclimate studies.
